Critical Over
Temperature
Internal hardware temperature
has exceeded the allowable limits.
Check to ensure external fans are
clear of debris and are operating.
-If external fans are not operating.
Contact Technical Support, fans
may need to be replaced.
7
Ground Fault,
Excessive Leakage
Current
A ground fault condition has been
detected. Leakage current is
greater than the allowable limit.
Check the array for an
unintentional reference to ground.
DO NOT TOUCH
any equipment
(including, but not limited to: the
inverter, the PV array disconnect
switch, the PV array combiners, the
PV panels, or the PV racking
system). Immediately contact the
installer or another qualified person
to locate and repair the source of
the ground fault.
8
Ground Fault,
Isolation Resistance
Low
A ground fault condition has been
detected. Insolation resistance
between the DC conductors and
ground is below the allowable
limit. Check the array for an
unintentional reference to ground.
DO NOT TOUCH
any equipment
(including, but not limited to: the
inverter, the PV array disconnect
switch, the PV array combiners, the
PV panels, the PV racking system).
Immediately contact the installer or
another qualified person to locate
and repair the source of the ground
fault.
9
Critical Internal
Hardware Failure
A critical hardware failure has
been detected to the inverter
powertrain.
Power cycle the inverter. If the
inverter doesn’t clear the error,
contact Technical Support.
10
Ground Fault
Detection Self
Check Failure
Ground fault detection circuitry is
damaged or has malfunctioned.
Power cycle the inverter. If the
inverter doesn’t clear the error,
contact Technical Support.
11
Operational Self
Check Failure
Inverter self-diagnostic check has
failed during operation. Inverter
requires service.
Power cycle the inverter. If the
inverter doesn’t clear the error,
contact Technical Support.
12
Startup Self Check
Failure
Inverter self-diagnostic check has
failed at startup. Inverter requires
service.
Power cycle the inverter. If the
inverter doesn’t clear the error,
contact Technical Support.
